Изобретение относитс  к способам обогащени  воды фтором.This invention relates to methods for enriching water with fluorine.

Известен способ фторировани  воды путем введени  в воду фторсодержащего соединени , в частности фторида кальпи , с раствором коагул пта - сернокислого алюмини . Однако по известному способу фторид кальци  плохо раствор етс  в растворе сернокислого алюмини  и образует тонкодисперсный осадок сульфата кальци , который образует отложени  в коммуникаци х и арматуре, что приводит к необходимости их периодической промывки и чистке.There is a known method for the fluorination of water by introducing a fluorine-containing compound into water, in particular, calpy fluoride, with a solution of coagulum aluminum sulphate. However, according to a known method, calcium fluoride is poorly soluble in aluminum sulphate solution and forms a finely dispersed calcium sulphate precipitate, which forms deposits in the communications and fixtures, which necessitates their periodic washing and cleaning.

Цель изобретени  - ускорение и упрощение процесса.The purpose of the invention is to accelerate and simplify the process.

Дл  этого по предлагаемому способу в качестве фторсодержащего соединени  берут кремнефториды, например Na2SiF6.To do this, according to the proposed method, silicon fluoride is taken as the fluorine-containing compound, for example, Na2SiF6.

Поскольку кремнефториды хорошо раствор ютс  в растворе сернокислого алюмини  и не образуют осадков, процесс осуществл ют в установках дл  приготовлени  рабочего раствора коагул нта. Способ исключает забивку коммуникаций и аппаратуры осадком, что значительно упрощает процесс.Since silicofluorides are well soluble in aluminum sulphate solution and do not form precipitates, the process is carried out in installations for preparing a coagulant working solution. The method eliminates clogging communications and equipment sediment, which greatly simplifies the process.

Пример. В бак емкостью 11,3 м с раствором сернокислого алюмини  удельным весом 1,08 кг/мЗ загружают 65 кг кремнефторида натри  (Na2SiF6), после чего ведут перемешивание сжатым воздухом. Спуст  3 час по окончании растворени  кремнефторида, полученный раствор перекачивают в расходные баки. Из расходных баков фторсодержащий раствор непрерывно через дозаторы поступает вExample. A tank with a capacity of 11.3 m with a solution of aluminum sulphate with a specific gravity of 1.08 kg / m3 is loaded with 65 kg of sodium silicofluoride (Na2SiF6), followed by stirring with compressed air. After 3 hours at the end of the dissolution of the silicon nefteoride, the resulting solution is pumped into the supply tanks. From the supply tanks the fluorine-containing solution continuously through dispensers enters the

обрабатываемую воду. При оптимальной дозе сернокислого алюмини , равной 45 иг/л, ука-занного количества раствора хватает дл  обработки 42 000-43 000 м воды. С учетом фтора в исходной воде около 0,3 Л1г/л содержаниеtreated water. With an optimal dose of aluminum sulphate of 45 IG / L, the indicated amount of solution is enough to treat 42,000–43,000 m of water. Taking into account fluorine in the source water about 0.3 L1g / l content

фтора в очищенной воде повышаетс  примерно до 0,8 мг/л.fluorine in purified water rises to about 0.8 mg / l.

Предмет изобретени Subject invention

Способ фторировани  воды путем введени  в воду фторсодержащего соединени  с раствором коагул нта, например сернокислого алюмини , отличающийс  тем, что, с целью ускорепи  и упрощени  процесса, в качестве фторсодержащего соединени  берут кремнефториды, например NaaSiFs.A method of fluorinating water by introducing a fluorine-containing compound into the water with a coagulant solution, for example aluminum sulphate, characterized in that, in order to accelerate and simplify the process, silicone-fluorides, for example, NaaSiFs, are taken as the fluorine-containing compound.
